Writing Ruby gems for RubyMotion

Laurent Sansonetti

RubyMotion projects can be extended through the use of RubyGems, the Ruby de-facto packaging system. This article will cover how to write RubyMotion-specific gems.

This article was inspired by Create gems for RubyMotion, by Francis Chong.

# Calculate your number according to http://www.astrology.com/what-numerology/2-d-d-66854
#
#
# HOW ARE NUMEROLOGY CALCULATIONS DONE
# In numerology, all numbers are reduced to the single digits 1 through 9 except the special master numbers 11 and 22. 1, 2, 3, 4, 5, 6, 7, 8, 9, 11 and 22 represent the major vibration rates associated with people’s characteristics.
# The numbers are reduced by simple addition. The number 15, for instance, is reduced by adding 1 + 5 to get 6. Similarly, the number 1974 can be reduced by adding 1 + 9 + 7 + 4 to get 21. The 21 can be further reduced by adding 2 + 1 to get 3.
# Letters in individuals’ names are converted to numbers and then added together. These numbers, in turn, are also reduced. The letter A, for instance, is 1; the letter B is 2; the letter C is 3, and so forth. The following table shows the numbers assigned to all 26 letters in the English alphabet.
# 
# 1 2 3 4 5 6 7 8 9

# Its still buggy and I would love some input on good usage of the NSRunLoop with MacRuby
